  2024-05-06

  

  Here, we investigate the ATM to ATR switch in normal human fibroblasts (82-6 cells) after irradiation with γ-rays, or high LET 56Fe and 28Si and moderate LET 16O particles. Our data provide important evidence of LET dependence on the transition of ATM to ATR as well as end resection at the sites of

  2024-05-06

  

  NO is an important mediator for maintaining bone integrity since it plays a role in the bone remodeling process. It was shown that mechanical strain and shear stress induce NO synthesis in osteoblasts and osteocytes (van't Hof & Stuart, 2001). It was reported that mechanical loading influences its a

  2024-05-06

  

  In addition, enhanced AT1 receptor function abnormally increases central and sympathetic activity, contributing to cardiac and renal disease, which in turn alters homeostasis, increases vulnerability to stress, and further injures the brain, and that AT1 receptor blockade ameliorates excessive sympa

  2024-05-06

  

  To date, attention has been directed towards new molecular targets in luminal phenotype (ER-positive), such as CDK4/6 and, to a lesser extent, androgen receptor (AR) pathways [8]. While the role of CDK4/6 has been elucidated and their inhibitors have shown a benefit in luminal BC, the role of AR in

  2024-05-06

  

  The 5′AMP-Activated Protein Kinase (AMPK) has evolved as an important cellular sensor of reduced energy status that can subsequently phosphorylate its target proteins, slowing the rates of key biosynthetic processes and promoting energy producing pathways; for these reasons AMPK has been proposed as

  2024-05-06

  

  Introduction AMP-activated protein kinase (AMPK) is mainly known as a highly conserved and ubiquitously expressed energy sensor that is highly sensitive to changes in cellular energy levels (by sensing increases in AMP:ATP and ADP:ATP ratios) and makes appropriate adjustment to balance the consumpt

  2024-05-06

  

  Cells have developed strategies aiming to enhance both the efficiency of proteins with chaperone activity as well as their overall antioxidant capacity to maintain proteostasis under oxidative stress conditions (Miyata et al., 2012). For instance, 2-Cys peroxiredoxin is an abundantly expressed, anti

  We have previously shown that the human gonadotropins hLH and hCG trigger a partly irreversible stimulation of intracellular cyclic AMP accumulation in mouse Leydig Tumor R406 mg (MLTC) in contrast to all other tested mammalian LHs and CG (Klett et al., 2016). In order to get a better insight in the

  Although the role of mossy fiber sprouting in epileptogenesis has been challenged (Elmer et al., 1997, Nissinen et al., 2001), in addition to astrogliosis, mossy fiber sprouting is one of the characteristic histopathological findings in TLE (Kharatishvili et al., 2006, Pitkanen et al., 2007, Represa

  In model plant Arabidopsis, there are 13 myosin XI isoforms (XI-1, XI-2, XI-A, XI-B, XI-C, XI-D, XI-E, XI-F, XI-G, XI-H, XI-I, XI-J, and XI-K) and 4 myosin VIII isoforms (ATM1, ATM2, VIII-A, VIII-B) [9,13]. Arabidopsis myosin XIs have the common domain composition: a motor domain that interacts with

  Given that there are 132 substitutions between βAnc and the human β subunit, we wondered whether βAnc could replace the human β subunit in hybrid AChRs formed from ancestral and human subunits. We first confirmed that the β subunit is required for expression of human AChRs in HEK293 Cepharanthine b

  Based on currently available knowledge, autophagy supports adipocytes development and differentiation. In animals with specific skeletal muscle PF-8380 of Atg7, reduced adipogenesis was shown. In rodents, autophagy was decreased in adipose tissue of animals fed with high-fat diet (HFD). In contrast,

  Enhanced arginase activity and the resultant decreases in L-arginine levels can also impair T cell mediated immune function and allow tumor growth by limiting the supply of L-arginine needed for the formation of cytotoxic levels of NO by iNOS [10]. Increased arginase expression/activity may also lim
